摘要:

AbstractProvided that the pathologist is experienced, frozen section diagnosis of suspected malignant melanoma of the skin is remarkably accurate. Not only can the pathologist diagnose malignancy but he can often indicate the level of invasion of the dermis by the tumour cells. This is a most important prognostic sign and guides the surgeon in his further management of the patient. The use of a cryostat is considered essential to allow better study of the cytological changes. The main indications for the technique are to make a precise diagnosis when there is suspicion of a malignant melanoma, and to confirm the clinical diagnosis before deciding on the extent of surgery. Its use in small tumours and for the detection of lymph node metastases is not advocated.A series of 329 frozen sections from 316 patients with an accuracy rate of 98.8 per cent is reported.

摘要:

AbstractThe rate of gastric emptying was estimated in 29 patients with duodenal ulcers, before and after vagotomy and drainage operations, by measuring the disappearance from the stomach of a standard meal containing radioactive chromium. When Heineke‐Mikulicz pyloroplasty accompanied vagotomy gastric emptying was observed to be slowed, whereas after vagotomy and Fitmey pyloroplasty the rate of gastric emptying was more rapid when compared with the preoperative rate. Gastric emptying after vagotomy and gastrojejunostomy showed no consistent alteration in rate. Temporary gastric stasis occurred in the early postoperative period after vagotomy and drainage procedure

摘要:

AbstractThe fecal excretion of bile acids was estimated in patients with postvagotomy diarrhoea, normal control subjects and a control group who had undergone truncal vagotomy and drainage but who did not have diarrhoea. The total daily bile acid excretion in the feces was significantly increased in the postvagotomy diarrhoea group: 2538 ± 632 mg (s.e.m.) compared with 799 ± 117 mg in the normal controls. There was no significant difference between the total daily bile acid excretion in the patients with postvagotomy diarrhoea and that of patients who had undergone vagotomy and drainage but who did not have diarrhoea. A significant increase in the fecal excretion of chenodeoxycholic acid was found in the postvagotomy diarrhoea group compared with the two control groups. This increase may be a factor in the pathogenesis of postvagotomy diarrhoe

摘要:

AbstractFive patients with incapacitating diarrhoea or severe dumping after vagotomy with pyloroplasty were treated by reconstruction of the pylorus. The operation was easily performed, and the postoperative course was unenventful in all the cases. All the patients had a significant improvement. The results suggest that pyloric reconstruction can be of benefit in patients who need revision operation for postvagotomy diarrhoea or dumping.

摘要:

AbstractTwenty‐one stomachs resected for carcinoma were studied histologically using the Swiss‐roll' technique. Chronic gastritis with epithelial hyperplasia was present in all.There were two types of distribution of the gastritis. In 17 instances it extended continuously from the pylorus proximally up to or beyond the carcinoma. This type of gastritis could be due to reflux of duodenal contents into the stomach. In 4 stomachs the gastritis occurred only in the vicinity of the tumour but did not extend from the pylorus and could therefore not be the result of duodenal reflux.It is postulated that there may be two kinds of carcinoma. One type is associated with the epithelial hyperplasia of chronic gastritis, possibly resulting from duodenal reflux into the stomach, The other is also associated with chronic gastritis but the distribution does not suggest duodenal ref

摘要:

AbstractThe effects of gastric tube replacement have been studied experimentally in dogs. A gastric tube can replace the lower oesophagus and, if maintained 2.5‐6 cm below the diaphragm, will prevent reflux.The gastric tube acts as a pressure barrier which is important in the prevention of reflux. Myotomy of the tube lowers the pressure barrier and allows free reflux. Atropine decreases the pressure within the gastric tube and gastrin increases the pressure within the tub

摘要:

AbstractOne hundred and forty cases of acute pancreatitis are reviewed of whisch 127 cases wee primary and 13 secondary acute pancreatitis. An association with biliary disease was found in 50 per cent of cases; 12.2 per cent of case were associated with heavy alcohol intake. In just over one‐third of cases no aetiological factor was identified.The overall mortality rate was 21.4 per cent; the mortality for primary acute pancreatitis was 18.9 per cent but only 5.5 per cent in patients under 50 year old. The mortality for secondary acute pancreatitis was 46 per cent. In primary acute pancreatitis operative intervention was associated with a 36.6 per cent mortality as compared with conservative management which had a 10.5 per cent mortality.The most important complication of acute pancreatitis was acute renal failure which accurred in 20 patients, 15 of whom died. Pseudocysts formed in 15 patients and were best treated by internal drainage, via cstogastrostomy where possibl
